#### Enabling the Gage Scan Filter

The gage scan filter improves the accuracy of circular feature measurements for the Adaptive Circle Scan and Adaptive Cylinder Concentric Circle Scan Adaptive Scanning measurement strategies. The filter uses parameters that are determined by gage scan calibration and stored in the probe file to correct measured scan data. The probe tip can be calibrated with an inside circle or an outside circle (or both).

To enable the gage scan filter:

1. From the Probe Toolbox, select the Measurement Strategies tab ().

2. Perform gage scan calibration for the active probe tip. This step determines the gage scan parameters for the given tip.

3. Use the Adaptive Circle Scan or Adaptive Cylinder Concentric Circle Scan strategy to measure a circular feature.

4. Select the Filters tab for the selected strategy.

5. Select the Use Gage Scan Filter check box. The calculation of the circle will use the gage scan filter data.

If the probe file does not contain any calibration data for the active probe tip, an error appears during measurement.
